Taken in by New York mob boss Arthur ten years ago, Valerie became the family's coldest enforcer and signed a five-year fake marriage pact with Raine, the playboy second son who secretly took bullets for her and cut off every suitor. When Arthur falls ill, his ambitious eldest son seizes territory and frames Valerie for her family's decade-old massacre. As the eldest moves to destroy her at the family round table, Raine drops his disguise: Valerie tears up the fake marriage contract before every mob boss, and Raine slams a loaded gun on the table, declaring she is his only woman. Guns raised, Valerie smirks and pulls the trigger—all-out family war erupts.
